"By the early 70s Riley had come to feel that scores were a distraction. Faithful interpretation of an already written piece was a deviation from the true purpose of making music, which was spiritual quest. Fortunately, some of those live performances, personal journeys towards a state of transcendence, were captured on tape. Persian Surgery Dervishes, issued initially on the French label Shandar, features two such concerts for electric organ and reel-to-reel delay, one recorded in Los Angeles on 18th April 1971, the other in Paris on 24th May 1972."
